Voxel51

Voxel51 builds FiftyOne, the open-source toolkit for building high-quality computer-vision and multimodal datasets and models. FiftyOne's primary interface is a Python SDK (datasets, samples, views, and the FiftyOne App) rather than a broad public REST API. FiftyOne Enterprise adds a Management SDK and an authenticated API connection that lets the SDK operate over the network instead of a direct database connection.

Voxel51 publishes 3 APIs on the APIs.io network: FiftyOne SDK (Python), FiftyOne Enterprise Management SDK / API, and FiftyOne Plugins & Operators. Tagged areas include AI, Computer Vision, Datasets, Machine Learning, and Python SDK.

Voxel51’s developer surface includes authentication, documentation, engineering blog, and 7 more developer resources.

  description: The open-source FiftyOne Python SDK is the primary interface for building and curating visual AI datasets -
    creating Datasets and Samples, slicing data with Views and aggregations, computing embeddings and similarity, running
    evaluations, and launching the interactive FiftyOne App. Distributed via pip (Apache-2.0); it is a Python library, not
    a remote REST API.

  description: FiftyOne Enterprise (formerly Teams) adds the fiftyone.management Python module for administering users, service
    accounts, API keys, dataset permissions, user groups, and cloud credentials. It operates over an authenticated API connection
    (FIFTYONE_API_URI + FIFTYONE_API_KEY) so SDK calls run against the central FiftyOne Enterprise API rather than a direct
    MongoDB connection. The wire protocol is an internal GraphQL/orchestration surface consumed by the SDK; Voxel51 does not
    publish a general-purpose public REST API contract.
